What to use instead of Cline: an open-source system your team owns
Cline is a good coding agent inside your editor, and it is open source. A team needs more than another editor agent: it needs a system the company owns. Kortix, the open-source AI Operating System, runs your agents on their own cloud computers and lands every change through a change request a person reviews.
The open-source AI Operating System

Questions people ask before they switch
What Cline is, what Kortix is, and the details people check first.
Is Kortix a Cline alternative?
Yes, on a different layer. Cline runs one coding agent on a developer's machine. Kortix is the open-source AI Operating System: it runs your agents on their own cloud computers.
Does Kortix replace my editor?
No. Kortix does not live in your editor: agents run on their own cloud computers, and the work lands as a change request you read as a diff.
Can I self-host Kortix?
Yes, and self-host is free. kortix self-host start pulls images from docker.io, so the machine needs internet access.
Which models can I use?
Any model provider with your own keys. Or the ChatGPT plan you already pay for.
Does an agent act without approval?
Approval gates you set. Off until you set them. You set allow, ask or block.
What does Kortix cost?
Free is $0 with 200 credits per month and 1 project. The team plan is $40 per seat per month with 2,500 credits per month per seat, pooled.
Is this site affiliated with Cline or the other tools on this page?
No. Cline and the other product names belong to their owners. We name them only to compare.
